Cool your heels with Louis Garneau's Versis socks. These socks are mid-ankle height and constructed of a Coolplus, poly, nylon, and lycra compound with mesh knit on the uppers and underneath the foot--a recipe for coolness and comfort in hot conditions.

These socks are great. Buy them...if you need socks. They will cover your entire foot (which is something I always look for in a sock). My only complaint is that they struggled to make me a better cyclist.
